Also, in talking to the department head of Purdue's aviation program who happens to be a meteorologist as well, he stated that altimeter settings are given for 10 feet above true. Is that to somewhat compensate for the distance from the altimeter in the cockpit to the ground (landing gear etc.)? In practice, how well does the altimeter in a small aircraft match up to reality once on the ground?
